v0 is Vercel's AI assistant for building web applications. You type what you want, such as a dashboard, a contact form or a small game, and it generates a working app that you can refine through further prompts. Templates for landing pages, components and apps help you get started.
Finished projects can be synced with a GitHub repository and deployed to Vercel with one click, so they go live as real websites. It suits developers, designers and founders who want to move from idea to prototype quickly.
